What are those sixteen compilers that are bastardizing you?:) [Open]Watcom seems to be up for the job (you can create 32-bit DOS programs with it). > However in dos > we have garanteed hard drive support via int13 (Well almost garanteed, > but if an os can boot of the computer, we can access the disk), The hard disk is not the only device you can boot off. Consider floppies, CDROMS, etc. etc. So your access to the disk is only guaranteed when you can read the disk, which seems like a tautology to me:). > and I'm looking for the same sorta garantee in BSD.

May I paraphrase: `If we have a disk which is unsupported by BIOS, we can just wash hands as we can't change the BIOS. If we have a disk which might be supported by FreeBSD but which we don't know the driver name for, we feel guilty, so we don't want that'. Is my understanding correct? There are not so many HDD drivers for FreeBSD out there. -- DoubleF Critic, n.: A person who boasts himself hard to please because nobody tries to please him. -- Ambrose Bierce, "The Devil's Dictionary" --Signature=_Thu__11_Mar_2004_15_51_19_+0300_+VcinV/QF1nXkX7I Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFAUGDiwo7hT/9lVdwRAoduAJ4op8v6/RAMd9ilxgysV10bDAB7VgCeNvwC IE9HOusQQSWVQbbnSUU2iYs= =em0i -----END PGP SIGNATURE----- --Signature=_Thu__11_Mar_2004_15_51_19_+0300_+VcinV/QF1nXkX7I--
